Experimental study of bone lengthening in dogs by means of backscattered scanning electron microscopy.

Objective: To describe the morphology of calcified tissues involved in distraction osteogenesis (DO) by means of backscattered scanning electron microscopy (BS-SEM).

Study Design: Experimental study.

Animals: Adult female Beagle dogs (n=12).

Comparison between meloxicam and transdermally administered fentanyl for treatment of postoperative pain in dogs undergoing osteotomy of the tibia and fibula and placement of a uniplanar external distraction device.

Objective: To compare the efficacy of meloxicam administered perioperatively with transdermal administration of fentanyl via a patch placed preoperatively in dogs undergoing orthopedic surgery.

Design: Prospective study.

Animals: 16 dogs.

Effects of static fixation and dynamization after interlocking femoral nailing locked with an external fixator: an experimental study in dogs.

Objective: To determine bone healing at 20 weeks, after either static fixation (SG) or after dynamization (DG) at 4 weeks in osteotomized canine femurs repaired with an interlocking nail (ILN) secured with a type I external skeletal fixator (ESF).

Study Design: Experimental study.

Animals: Ten adult beagle dogs.

Use of distraction osteogenesis for the correction of deviated nasal septum and premaxilla in a horse.

A 13-month-old female Andalusian was evaluated because of a congenital left deviation of the maxilla and nasal septum, which had resulted in a gross malocclusion of the maxillary incisor teeth. Surgical correction of a deviated nasal septum and premaxilla in a horse was first reported in 1978 and involved a pre-maxilla osteotomy and use of an autogenous rib graft, with a nasal septum osteotomy performed in a second surgery; to the authors' knowledge, no alternative surgical treatments have since been described. In this horse, a new surgical treatment by distraction osteogenesis without nasal septum osteotomy was attempted.
